I woke up 3 days ago and I had a very dry tongue, it was sensitive as if i had burnt it. My frenulum under my tongue was swollen and I have white bumps on it as well as around my gums. My entire mouth is sensitive. Not really painful, just sensitive. Ive had a huge month at work, and I assume my immune system is really low, as I had a cold and cold sores the week before. should I be worried.
